Product FAQs
6 answersWhich panelboards accept the HE63B080 circuit breaker?
This bolt-on breaker is designed for installation in Siemens P1, P2, and P3 panelboards, as well as legacy ITE panelboards.
Is the Siemens HE63B080 the same as the ITE HE63B080?
Yes. Siemens acquired ITE, and the HE frame is a legacy ITE design. Breakers labeled as ITE HE63B080 or Siemens HE63B080 are the exact same component and are fully interchangeable in existing enclosures.
How does the HE63B080 connect to the panelboard bus?
The HE63B080 is a bolt-on circuit breaker. It secures directly to the panelboard bus using bolted connections, which provides a secure, high-vibration-resistant installation compared to plug-in alternatives.
What wire sizes and materials are supported by the HE63B080 lugs?
The factory-installed load lugs accept 10 AWG to 1/0 AWG wire. The terminals are dual-rated for use with both copper (Cu) and aluminum (Al) conductors.
Can the HE63B080 be used in direct current (DC) applications?
Yes, in addition to its standard AC ratings up to 600VAC, this thermal-magnetic breaker is rated for use on DC systems up to 250VDC.
Does the HE63B080 feature adjustable trip settings?
No, this breaker uses fixed thermal and fixed magnetic trip elements for long-time and instantaneous (LI) protection. The trip points are factory-set and cannot be adjusted in the field.
